- Activity: If you're heading on a canoe or kayak trip, you'll want to be sure your first-aid kit is waterproof. Look for waterproof kits or place your kit inside a plastic freezer bag then slide it into a dry bag to ensure your medical supplies stay dry.
- Group size: Scout leaders or families traveling together in a larger group will want to make sure that someone carries a "group" first aid kit to handle a wider scope of problems that might arise. These kits build on the basics in your personal kit by adding more (and different sized) bandages. They're also include items like tweezers, a thermometer and splints. Bigger kits also make sense for car campers or for use at home where weight isn't a factor.
- Assess The Risks: What might you encounter in the area you're heading to? Are their people in your party that have specific allergies where items like an EpiPen may be needed? Is there a high risk of ticks being in the area? If so, you'll want to purchase a kit that includes tweezers or a tick-removal tool. If there's a good chance you may encounter poison ivy or sumac, make sure the kit includes some kind of treatment for treating anyone who gets exposed.
